Learn Turkish: Sokakta ganimetleri taşıyan taşıyana. - People are carrying the loot in the street left and right.

This is the chaotic abundance structure from this lesson. It uses the subject participle -An (the one who carries) and repeats it with the dative case -(y)a to make taşıyana (to the one who carries). The literal phrase "the carrying one to the carrying one" creates a vivid picture of a crowded, chaotic scene where everyone is doing the action at once.

Where is the main verb in this sentence?

There isn't a standard conjugated verb! The taşıyan taşıyana idiom acts as the entire predicate. It implies a state of being, meaning "There is a chaotic scene of people carrying...", so no extra verb like taşıyorlar is needed to finish the sentence.

Why does ganimetleri have the accusative ending if the sentence lacks a normal verb?

Participles like taşıyan retain the grammatical properties of their root verbs. Because the root verb taşımak (to carry) takes a direct object, its participle can too. Since "the loot" is a specific, defined object being acted upon here, it requires the accusative suffix -i.

Why is ganimetleri plural when the English translation just says "the loot"?

English treats "loot" as an uncountable noun, but the Turkish word ganimet is countable. Because this scene involves many pieces of captured or stolen goods scattered about, it naturally takes the plural suffix -ler before the accusative ending.
